hi, my sister's hb was throwing a 02 sensor code, i guess the last time the 02 was changed they didn't put any antiseize on the thread and it [freak]ed up the thread of the manifold. i can't find a tap big enough to retap. so does anyone have a exhaust manifold laying around? am located in so cal. LA area. please letme know thanks.

 

thats an easy fix cut as much of the o2 sensor off as you can then drill it out
